TM Tgard 20 Thermally Conductive Insulators LOW COST, MEDIUM PERFORMANCE INSULATOR MATERIAL TM The Tgard 20 is designed to solve over heating issues such as lower component efficiency, premature component failures, size limitations and other performance problems for todays computer power supplies. TM The Tgard 20 is a film-based product designed to resist cut through in screw mounting applications while providing a more consistent breakdown voltage over other insulator constructions. The phase change coating on the film core provides an excellent mating surface for low pressure clip mounting applications. PERFORMANCE CAPABILITIES High dielectric breakdown of 9,000 volts Film base resistance cut through 2 Thermal resistance of 0.60C-in / watt 25 psi pressure FEATURES AND BENEFITS APPLICATIONS Reinforced with moderate temperature Switching mode power supplies for: resistant film - Computers High voltage resistant film - Consumer electronics Total thermal resistance of 3.4C/watt UPS units on TO-220 Non-blocking for ease of use Designed for computer power supplies global solutions: local support TM Americas: +1.800.843.4556 Europe: +49.8031.2460.0 Asia: +86.755.2714.1166 CLV-customerservice lairdtech.com www.lairdtech.com/thermalTM Tgard 20 Thermally Conductive Insulators PROPERTY TEST METHOD METRIC VALUES IMPERIAL VALUES ELECTRICAL PROPERTIES Dielectric Withstand Voltage ASTM D149 4,500 volts DC 4,500 volts DC Dielectric Breakdown Voltage ASTM D149 >9,000 volts AC >9,000 volts AC 12 12 Volume Resistivity ASTM D257 >10 ohm-cm >10 ohm-in Dielectric Constant 1 MHz ASTM D257 1,8 1.8 MECHANICAL PROPERTIES Thickness 0,076 mm 0.003 inch Substrate Film Thickness 0,051 mm 0.002 inch Tensile Strength ASTM D412 138 MPa 20 kpsi Elongation ASTM D412 130% 130% Operating Temperature Range -40 - 150C -40 - 302F Color White White UL Flammability Rating UL 94 V0 V0 PRESSURE, PSI (KPA) UNITS 10 (69) 25 (172) 50 (345) 100 (689) 200 (1379) TOTAL THERMAL RESISTANCE 2 Modified ASTM D5470 C-in /watt 0.65 0.60 0.60 0.60 0.60 2 Modified ASTM D5470 C-cm /watt 4,2 3,9 3,9 3,9 3,9 TO-220 C/watt 3.8 3.4 3.4 3.4 3.4 STANDARD THICKNESS: STANDARD ROLL SIZE: DIE-CUT PARTS: 3 mils (0,076 mm) 12 x 300 Standard and custom (304 mm x 91 meters) configurations available Data for design engineer guidance only.
